Apologies for the delay. The problem does persist.
We are using the 2017 release AutoCAD Mep w/ Fabrication MEP.
The save locations are different sub folders within job folders on a network drive. However, I got the same result saving both copies to my desktop or local documents folder.
I can provide you a copy, but not sure it would help. The process is run a customer command, saveas (1) - success, saveas (2) - fatal. When the savedas(1) file is reopened and saveas is run again is works just fine. So i could run the command and then save and send to you, but the saveas/saveas doesn't seem to be an issue when the file is closed and reopened.
The custom command is essentially a command that cleans the drawing to send outside the company for coordination, effectively removing everything but the pipe/duct necessary for coordination. The command itself runs without issue, but seems to create the saveas/saveas fatal issue. The easy solution would be for those handful of users to change their processes, because they should be saving the original file to the 1st location before running the custom command anyway. That would then only require 1 saveas to the 2nd location and never fatal. Nevertheless, the issue did intrigue me, hence the inquiry.
